Introduction to 8mm UV LED Technology
What is an 8mm UV LED?
The 8mm UV LED, as the name suggests, refers to an ultraviolet light-emitting diode with a diameter of 8 millimeters. UV LEDs are a type of solid-state lighting that emit light at wavelengths between 10 and 400 nanometers, which fall within the ultraviolet (UV) portion of the electromagnetic spectrum. Unlike traditional UV lamps, UV LEDs are more energy-efficient, have a longer lifespan, and are more environmentally friendly. The 8mm size of these LEDs makes them versatile for various applications, including curing, disinfection, and sensors.
How Does an 8mm UV LED Work?
An 8mm UV LED operates based on the principle of electroluminescence. When an electric current passes through a semiconductor material, it excites the electrons within the material, causing them to jump to a higher energy state. When these electrons return to their original state, they release energy in the form of light. In the case of UV LEDs, this light is in the ultraviolet range. The size of the LED, such as the 8mm diameter, determines the intensity and focus of the UV light emitted.
